密码认证方式(认证加密方式)

小编：迷魂雪更新时间：2022-05-01

简介

对于安全认证来说，也是无线比较重要的一块，在SOHO级别以及小型环境中，比较倾向于预共享的方式进行认证，也就是配置一个大家知道的密码，输入后就能连接到无线网络，常用的有WEP、WPA、WPA2，WEP已经渐渐的淘汰了，非常容易被破解，推荐的是WPA2的AES，对应小型环境或者SOHO级别的来说还是比较容易部署的。当然认证还有很多，比如基于MAC地址认证、dot1x方式或者portal网页认证等，这些方式会在后续陆续演示。

掌握目标

1、AC的基本业务配置
2、认证方式的配置

拓扑写了对应的IP网段，以及各自的VLAN信息，可以对应配置看

路由的配置

interface GigabitEthernet0/0/0
ip address 10.1.200.1 255.255.255.0
#
interface LoopBack100
ip address 100.100.100.100 255.255.255.255
#
ospf 1 router-id 1.1.1.1
default-route-advertise always
area 0.0.0.0
network 10.1.200.1 0.0.0.0

AC的配置

#
interface Vlanif100
ip address 10.1.100.1 255.255.255.0
dhcp select interface
#
interface Vlanif101
ip address 10.1.101.1 255.255.255.0
dhcp select interface
dhcp server dns-list 8.8.8.8
#
interface Vlanif102
ip address 10.1.102.1 255.255.255.0
dhcp select interface
dhcp server dns-list 8.8.8.8
#
interface Vlanif103
ip address 192.168.103.1 255.255.255.0
dhcp select interface
dhcp server dns-list 8.8.8.8
#
interface Vlanif200
ip address 10.1.200.2 255.255.255.0

说明：该VLAN接口地址一个是用于与AR路由器相连，其余的是作为无线客户端的网关

interface GigabitEthernet0/0/1
port link-type trunk
port trunk pvid vlan 100
port trunk allow-pass vlan 100 to 102
#
interface GigabitEthernet0/0/2
port link-type trunk
port trunk pvid vlan 100
port trunk allow-pass vlan 100 to 102
#
interface GigabitEthernet0/0/3
port link-type access
port default vlan 200

说明：这里由于AP是双频的，也可以每个AP发送多个SSID，所以要允许对应的VLAN流量。

interface Wlan-Ess0
port hybrid untagged vlan 101
#
interface Wlan-Ess1
port hybrid untagged vlan 102
#
interface Wlan-Ess2
port hybrid untagged vlan 103
